52 Claims.

This invention relates to an improved applying machine, the features of which are capable of use in numerous diiferent associations, but which are primarily intended for employment in connection 5 with the manufacture of receptacles such as paper boxes and their parts.

By means of the present invention an apparatus is provided which will embody relatively few parts, each individually simple and rugged in construction and capable of assemblage to furnish a machine operating for long periods of time with freedom from difiiculty and the necessity of manual supervision.

It is another object of the invention to provide a machine of the character described embodying improved mechanism capable of operation at relatively high speeds, and which will operate in an improved and efficient manner to prevent clogging of the machine or the forming of imperfect receptacle parts in any case where the receptacle forming material is not properly supplied.

A further and more particular object of the invention is to provide, in a machine of the class mentioned, an improved mechanism operating 25 with efficiency and rapidity for applying and adhesively attaching layers of material, such as finishing strips, to the surfaces of boxes or receptacle parts.

Other objects of the invention will be in part pointed out in the following detailed description of an illustrative but preferred embodiment of the invention, and will be in part obvious in connection therewith.

3 The invention accordingly comprises the fea- 35 tures of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described, and the scope of the application of which will be indicated in the claims.

Fig. 18 (Sheet 2) is a face View of a control disk or plate shown in assembled position in Fig. 4.

For a detailed description of the illustrative but preferred embodiment of the invention, reference is first made to Figs. 1 and 2, showing the deck 20, supporting the two principal units of the machine including turrets Zi and 22. The turret 2| receives and retains the box or receptacle part to one end of which a blank or finishing strip, herein shown in the form of a disk of paper, is applied through the cooperation of the turret 22.

As shown in Fig. 3, the receptacle parts are in the form of cylindrical box bodies, as indicated in dot and dash outline, these being moved to the machine along a downwardly inclined runway including a base or supporting plate 23 to which upright side strips 24 or guides are adjustably attached by bolts 25 riding within slots 26 of the brackets El secured by clamps 28 to the base plate. By means of this structure, the height of the sides or guide rails 24 may be easily varied, and the width of the chute may also be readily varied by a lateral adjustment of the clamps 28.

Some types of receptacle or box parts handled by this machine have flange or side wall portions which are quite fragile and considerable care must be exercised in order to avoid damage to these parts. Therefore, the receptacle of this type, which is about to be introduced into the machine should be somewhat segregated from the following receptacles. Of course, where flange portions or their equivalents do not form parts of the receptacles, it is usually unnecessary to utilize a segregating mechanism. As will be noted in Fig. 3, this mechanism may include a rocker arm 29 adjustably carried by a bracket 30, and at the ends of this arm, springs or spring fingers 3! are secured so that the receptacles or other material being handled by the machine may be engaged to allow the lowermost receptacle in the chute to move downwardly, while holding the remaining receptacles in spaced relation thereto. The rocker arm may be guided by a crank arm 32 secured to a link 33, with which the spring 34 is coupled. The spring serves normally to urge the outermost contact finger downwardly, but the link may be reciprocated to swing the parts to the other extreme position by any suitable operating means connected to the link, such as an arm 35 secured to a shaft 36. The mechanism for oscillating this shaft will be hereinafter described. Adjacent the lower end of the chute the side Walls thereof may terminate. In line with points beyond the same are a series of angularly spaced, radially adjustable guides 31, the outermost of which have foot portions 38 which act to prevent the receptacle from moving along the chute beyond a predetermined point.

In line with the center, as defined by the radially extending guide and stop members 31, is the axis of a unit which transfers the receptacle parts or other material from the chute to the turret 25. This transfer unit, as shown especially in Fig. 9, may include a cylinder 39 within which a piston reciprocates. Movements of this piston beyond a predetermined point are prevented by an adjustable stop 4i and secured to the piston is a rod 42 which extends through a stuffing box 43 and terminates in a head 44 of an area such that it may pass through the space defined by the inner ends 33 of the guides 31. The head 44 may carry a guide or stop 45 which extends towards the chute and supplements the action of the segregating mechanism if the latter is employed. In other words, as the head is projected, this guide rides against the side edge of that unit of material which is next to be fed to the machine and prevents the same from moving to a position at which it might becomeinjured. Reciprocation of the piston and head is effected by coupling the ends of the cylinder through tubes 45 with a source of fluid pressure.

As clearly shown in Fig. 1, the transfer unit or plunger 44 is disposed beyond the inclined article or box body chute while the turret 2| is disposed at the opposite side of the chute and in line with the transfer head 44. The turret 2| includes a central hub portion 41 from which angularly spaced supporting arms 48 extend outwardly, carrying outwardly disposed article supporting heads or mandrels 49. As best shown in Fig. 5, each of these supporting heads includes a cup--shaped box supporting member 50 having grooves in its outer face and being attached to its supporting arm 66 by a bolt 52 having an aperture or conduit extending therethrough and communicating with openings 53 leading to the grooves 5i.

When a receptacle or other unit of material moves down the runway and assumes a position in line with the space defined by the inner ends of the guides 31 and thereupon the head 44is projected to push this unit of material towards the head 49, it will be obvious that the unit will be mounted thereon and be retained thereby, especially if the bore of the bolt 52 is connected with a source of vacuum. Conversely if fluid under pressure flows through the bore of the bolt, the unit will be ejected from the head. In order that fluid may pass through the bore of the bolt in the manner described, it will be seen that the arm 48 is formed with a bore 54, with which the hollow bolt communicates. Each bore 54 is continued in the form of a branch extending to the side face of the hub element 41 of which the arms 48 form a part. Overlying this side face is a rotatable disk 55 which, as shown in Fig. 8 has a series of grooves or ports in its side face. As shown, thesegrooves are in the form of arcs of acommon circle and are identified by the reference numerals 56, 51, 58 and 59. The first and third of these are connected by tubes 60 with a source of suction (not shown). The channel 59 is connected with a source of fiuid pressure (not shown) by means of a tube 6|. A tube 62 extends from the channel or groove 51 and the purpose of this latter tube will be hereinafter brought out.

As best shown in Fig. 4 the turret 22 includes a body or hub 63 from which arms 64 extend. Adjacent the outer ends of the arms, collars 65 are provided, these collars slidably mounting rods 66 which are normally urged upwardly by means of encircling springs 61. At their lower ends the rods carry heads 68 which embrace perforated face plates 69. The hub 63 slidably supports a rod 16 carrying arms 1! having their ends positioned for alignment with the upper ends of rods 66. Adjustable contact members 12 are mounted by both of the arms 1| and it will be obvious that if the rod 16 is retracted with reference to the hub 63, these contact members would come to bear against the upper faces of the rods 56, thereby depressing the heads 68 against the resistance of the springs 61. The hub 63 terminates in a base portion 13 housing one or more downwardly extending springs 14 which bear against the upper face of a plate 15, best shown in Fig. 18. The plate in turn rests upon a base 16 and a member providing a side wall 11 is secured to the base 13 and overlaps plate 15 and the upper edge of the base 16, it being noted that this member is formed with a circumferential series of perforations 18, which are normally in line with the side edge of the plate 15. The faces of the base portions 13 and 16. are best shown in Figs. 6 and 7 respectively, wherein it will be noted that the base 13 is formed with ports 19, and with a series of recesses which accommodate the springs 14. Connected to the ports are tubes 88 which extend one to each of the heads 68. groove 8! formed in the face of the base, it being noted that each port is framed by a downwardly extending flange member 82 extending into the groove 85 and terminating in the same plane as the lower surface of the base 13. The plate 15 has openings 83 in line with the ports 19 and bolts (not shown) extend through further 0pen-,

lugs 54 of this plate into openings 85 formed in theupper base 13. Thus the plate 15 is mounted to rotate with the upper base, but the bolts are so adjusted that the plate will rest upon the base portion 16, and that the base 13 may move towards and away from the plate 15, it being of course obvious that, with the plate intimately in contact with the lower face of the base 13, fluid will flow directly through the openings 83 and the The ports 19 open into an annularports 19, while if the plate is spaced from the 5 K, pin 90 more than a semi-circle.

base, the ports I9 will be interconnected through the groove 8|;

The base or hub I6, as shown in Fig. 7, is formed with a groove 86, which extends through slightly The groove is in constant communication with at least one of the openings 83 and, by means of a tube 81 is connected preferably to the same source of suction (not shown) as that to which the tube 69 of turret 2| is connected. A tube 88 is also connected to the groove and this tube is either identical with, or else connected to the tube 62 shown in Fig. 8, thus communicating through the conduits 54 (Fig. 5) with the heads 49.

The base or hub portion I6 is mounted for rotary oscillation upon a standard 89 and has a which is connected to an actuator 9|, best shown in Fig. 11. This actuator takes the form of a fork at the outer end of a rocker arm, which latter is link-connected, as at 92, to a crank 93 connected by a link 94 to a follower cooperating with a cam 96. The cam is mounted by a shaft 91 which is driven in a manner hereinafter brought out, and it will be observed that this shaft carries a cam 95 cooperating with a follower 99 link-connected as at Iilil to a lever NH. The lever is pivotally mounted and normally has its outer end urged downwardly by a spring I22. Adjacent this outer end the lever IUI may have notched portions which cooperate with the centering extensions I02, which may be V-shaped in cross section.

Accordingly, with the shaft 91 rotating, the lower base section or hub I6 will be periodically oscillated, while the arm IIJI will cooperate with the edge portions of the extensions H12 in order that the arms 64 and heads 68 carried thereby may be accurately and periodically aligned with the operating contact elements "I2.

As has been previously brought out, the turret 22 is to receive material and apply the same to the receptacle part carried by the turret 2|. Preferably, the material supplied to the turret 22 comes from a magazine (see Fig. 2), having vertically extending guide members I03, defining between them a space sufficient for the accommodation of a stack of blanks I94. This magazine is disposed in line with rest positions of the heads 88 of the turret 22 and a base I05 forms a part of the magazine and serves to elevate the stack of blanks so that the uppermost may cooperate with the turret head. This elevation is achieved preferably by employing a screw-threaded rod I95 which passes through a similarly threaded nut I91, and which nut is rotated by employing a pawl and ratchet mechanism I99. The nut I01 is preferably of the more or less conventional type which is split and capable of being opened by actuation of a handle I09 so. that the shaft I96 may be manually elevated or depressed.

In moving from the magazine station to the station at which the blank is delivered to the re ceptacle part carried upon one of the heads 49, the head 68 passes a glue roller IIO, best shown in Fig. 1. This adhesive applying roller may take any desired form and include, for example, a plurality of annular ribs, and is rotated by means of a sprocket gear III and partially immersed within a glue tank I I2. Thus, if a blank is carried by the head 68 and the latter is in depressed position, it is obvious that the lower face of the blank will come in contact with and be coated bythe glue roller.

When the blank isadhesively treated as de- 49 of the turret will be subjected simultaneously to the following scribed, the head 68 continues its rotary movement in its relatively depressed position until it comes into alignment with the mandrel or head 49 at Station B. At this point the operating arm II descends (see Fig. 4), thus moving the carrying head 68 downwardly and causing the adhesively treated blank to be pressed into contact with the surface of the box blank or part supported upon the mandrel 99. In this manner the blank or strip is adhesively attached to the box part whereupon the suction grip of the head 68 upon the blank will be released and said head will be retracted and its rotary movement continued at the next operative cycle.

In certain instances, it is desirable that the blank transfer at this initial applying station should be supplemented by an action whereby the blank is forced into intimate contact with the surface to which it is applied. Thus as shown in Fig. 1, a fluid cylinder H2 serves to reciprocate a pressing pad I3 to engage the outer face of the blank and to yieldingly press the same into engagement with the box or other article on the head 49. As best shown in Fig. 10, the cylinder I i2 may be divided into sections by a central wall 5 I4 and within each of these sections pistons H5 reciprocate in directions controlled by the flow of fluid through tubes H9. The pistons ||5 are coupled by a rod II'I which carries at its outer end the pad H3 and it is thus obvious that the desired pressure may be transmitted to the outer face of the blank.

When cylindrical boxes are being handled and blanks, such as finishing strips or labels, are to be applied to the box parts, a supply of such parts is delivered into the inclined chute shown in Fig. 3. Also as shown in Fig. 2 a supply of blanks I94 is disposed in the supply magazine. The motor H8, through a reduction gearing H9 and a clutch i233, serves to drive a. shaft I2I which, by means of gears i22 rotates the cam shaft 91. By means of a Geneva movement I23, best illustrated in Fig. 12, an intermediate rotation is imparted to the shaft I24 to which turret 2| is operatively connected. Also coupled to this shaft is a bevel gear I25 which meshes with a gear I25 coupled with a sleeve or tube I2'I connected to the hub 63, as shown in Fig. l. The ratio of gears I25 and I25 is l to 2 so that for each revolution of the shaft I24 the sleeve I2'I is turned through two complete revolutions. As shown in Figs. 2 and 12, the shaft I2I carries a gear I28 meshing with a gear I29 on a shaft I38 carrying a sprocket I 3| meshing with a sprocket chain I32 which is connected to the sprocket III of the adhesive roller Ill) shown in Fig. 1. Therefore, by the mechanism described both turrets 2| and 22 are intermittently rotated through operation of the Geneva stop movement, and the periods of rest resulting from this drive occur when one of the mandrel heads 49 of the turret 2| is adjacent to the plunger head 44 of the box transfer device. The next advance head of the turret 2| extends vertically under the head 68 of turret 22; the third head ofturret 2| extending during this period in line with the head or pad H3, and the fourth head extending downwardly in line with a discharge opening I33 adjacent which a chute 533 may be disposed. Obviously, during these periods of rest the two heads I58 overlie the uppermost head 59 of the turret 2| and the blank supply magazine, respectively. Referring to Fig. 1. it will now be apparent that the mandrel heads 2| and the box parts thereon operation of the plateor head II3; fourth: the

completed receptacle part will be expelled at station D from the mandrel head into the chute I33 provided therefor. Since all of the dilferent operating steps mentioned are simultaneously performed after each successive shift of the turret 2!, it will, therefore, be seen that a-box part is completed at each such shift.

Obviously, the head IQ-adjacent station A, is. in communication through its bore 54 with port 56 so that the receptacle delivered to it will be drawn into intimate contact with the head portions. Immediately thereafter port 51 communicateswith the branch and bore connected to this .head, the purpose of this construction being also hereinafter brought out. As the head reaches station B, at which the disk is applied, its branch and communicating bore 54 are connected to groove or port 58 :so that from this point on, and through and beyond station C, the material carried by the head is continuously subjected to the action of suction to insure against its being displaced from said head. Adjacent the fourth or discharge station D the port 59 communicates with the bore 54 and its branch and air under pressure will now flow to the head to expel the completed article. It will be understood that the plate is shifted by mechanism hereinafter described so that the vacuum and pressure effects wi1l occur with sufficient force.

As shown in Figs. 4, 6, '7 and 14, it will be noted that the rod Ill and arm "II of the turret '52 reciprocate and rotate with respect to the hub 63 and head portions 68 associated therewith. This ,result is achieved by means of a lever I34 coupled to the lower end of the rod '19 and which has a second arm connected to a rod I35 and spring I38. Rod I35 is coupled to a follower 13?, as shown in Fig. 14, and this follower rides against the surfaces of a cam I38 with which it i is pressed into contact by the spring I35. Ob-

viously therefore, as the shaft 91 rotates, the cam will cause the rod I9 to be periodically elevated and lowered, and this will in no wise interfere with the rotation of the hub 63 and its associated parts. The cam is so timed that the arms flI lower when the heads 68 are located respectively under these arms and in line respectively with the magazine carrying blanks I 94 and the uppermost head 49 of turret 2i at stationA. Such lowering will cause each rod 66 to be depressed against the .action of its spring 61, resulting in the lower face of one plate 69 being pressed into contact with the uppermost finishing strip or disk in the magazine, while the lower face of the second head plate 69 is moved towards theupper surface of the receptacle carried by that head 49 which occupies station B. This downward movement of the heads 68 will obviously place the springs "I4 under compression and move the base '53 into contact with the plate I5, said springs being sufiiciently weak as compared with the springs 61 to accomplish this result. With the tubefiI connected to a source of vacuum supply and the perforations of the plate 69 of both heads sealed by disks,,it is apparent that the suction will act through the groove 86, openings or ports 83 and ports 19 to transmit the suction so as to-retain the disks inintimate association with the under faces of the plate 69,- and to retain the plate I5 in intimate contact with the base 73, due to the fact that the openings I8 in the annular sealing plate T! will be sealed. This, of course, is conceding that air may not enter through tube 88. Such entry of air isprecluded if a receptacle has been received by the head 49 adjacent station A ofturret 2| so as to close the grooves 5I- and openings 53 and consequently when the channel or port 51 is connected to the bore 54, no air flow will occur through the latter nor through the tube 62, nor, consequently, the tube 88.

Therefore, the base I3 will remain immediately adjacent the plate 15, with the springs I4- under compression. If, however, no receptacle has been applied to the head 49 at station A, it is obvious that air will'be free to flow through the bore 54 and so through tube 62 and tube 88, as a consequence of which-the vacuum throughport'19 and tube 89 will be broken. When this occurs it is patent that the base I3 will rise under the in fluence of springs 14 and the initial position of the parts may not perforations I8 will now be uncovered, thus suffioiently breaking the suction to prevent this occurring. If, as will be normally the case, receptacles seal the bores 54 of the heads 49, then of course the base I3 will remain lowered and consequently as the arm 64 swings the head 68 past the glue roller, the underface of the disk carriedby the head will come in contact with such roller and be guided thereby. However, if no receptacle is present and the hub 63, together with its associated parts is elevated, the under face of the plate 69. will clear the roller and the disk will remain uncoated.

In each instance, after the hub 13 has been elevated, it will be apparent that under normal operation, the machine will endeavor to reestablish the proper cycle of operation, due to the fact that the rod pressingthe head 68 downwardly and compressing the springs 'I4incident to greater resistive force offered by the springs 6'I.' Again, however, if no receptacle is present upon the next head 49 of the turret 2|, the springs 14 will again re'-' establish the inoperative condition of the parts. Consequently, any diskor blank picked up by the heads 68 will simply remain uncoated and be loosely deposited upon the head 49 occupying station B. Thereupon, and as turret 2| rotates, this disk will drop clear. Through operation of the mechanism shown in Fig. 11 the proper positioning of the heads 68 is at all times assured, as is also the shifting of the control base or disk I6. In connection with the latter it will be understood that as in Fig. 7, the groove 86 extends preferably in excess of 180. This permits of suction acting on both heads 68 as they are depressed incident to the retraction of the rod I0. Consequently the one blank or disk is retained while suction tends to draw the uppermost disk in the magazine into contact with the second head. At that moment, the disk I6 shifts so that suction to the first head is interrupted and the adhesively treated disk associated therewith' will be retained in contact with the receptacle applied to the uppermost head 49 of the turret 2 I. The pawl and ratchet mechanism I08 for feeding be re-established, because the III will reciprocate, thus" the blanks I04 in the magazine (see Fig. 2) may be actuated, as shownin Fig. 15, by a rod I39 which is normally spring-projected, as at I40, and is capable of retraction by means of bellcrank levers and links MI in turn coupled to a follower I42 cooperating with cam I43 secured to shaft 91.

Referring to the remaining controls illustrated, it will be observed, as in Fig. 13, that a cam M4 may be secured to the shaft 91 and cooperate with a follower I46 which is coupled to the shaft 36 in order to reciprocate link Referring next to Fig. 14;, it is to be observed that the gear I22 carries on its outer face a cam shoe Hi1 which cooperates with a valve control I48 in order to connect a cylinder I49 to a source of fluid under pressure. Extending from this cylinder is a rod I50 which is connected or forms a part of rod I35. Consequently, bellcrank lever I34 is shifted in one direction by the cam I35 but rocks in the opposite direction by virtue of the spring I36 as well as under the action of fluid pressure.

As shown in Fig. 16, the toothed gear I22 carries a cam element I5I with which a follower I52 cooperates. This follower is normally springretracted as at I53 and is link-connected as at I54 to a valve I55. This valve controls the flow of fluid from a source of pressure (not shown) through tube 6| as described in connection with Fig. 8.

Finally, referring to Fig. 17, it will be noted that the shaft 91 additionallycarries a cam I56 cooperating with a follower I5? which is springpressed, as-at I58, and is connected by link I59 to a valve Hi0. This valve is connected by a tube I6I to the source of fluid under pressure and extending from such valve are the tubes 46 and H6 controlling the cylinders shown in Figs. 9 and 10, respectively.

From the foregoing it will be understood that a machine is provided which is capable of use in numerous different associations, but which is of primary utility when employed in the manufacture of receptacles. In such association it will serve effectively to handle receptacle portions and to apply thereto end disks. If for any reason a receptacle part is not applied at Station A upon the mandrel head of the turrett 2| the vacuum at the suction head 68 positioned at the magazine carrying the blanks I04 (see Fig. 2) will be broken, and consequently one of the blanks or finishing strips will not be picked from the magazine as the head 68 rises upon retraction of the operating arm II. At the same time, the vacuum in the channel or chamber ill (see Fig. 4) will be broken and the turret 22 together with the. heads 68 will be moved upwardly slightly due to the expanding action of the springs I4, thus positioning the head 63 moving past the adhesive roll H0, so that said head does not contact with the roll. In this manner, application of the adhesive to the surface of the. plate 69 of the head 68 is avoided entirely eliminating smearing or continuation of the parts.

Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
